STUMP-PULLER.

Specification of Letters Patent.

Patented Feb. 2'7, 1966.

Application filed February 7, 1905. Serial No. 244,606.

To all whom, it may concern:

Be it known that I, JOHN K. .FLYNN, a citizen of the United States, residing at Duluth,-

in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Stump -Iullers, of which the following is a specification.

My invention relates to stump-pullers of the drum-and-lever class, and has for its obj ect the provision of a device for keeping the cable taut on the drum, consisting of two sheaves suitably mounted, between which the cable runs, said sheaves being adjustable relative to one another and one of said sheaves geared to the drum, so as to rotate at the same speed therewith. The construction, operation, and advantages of my invention will befully explained hereinafter and illustrated in the accompanying drawings, in which Figure 1 is a side view of a Windlass stumppuller, showing my invention applied thereto Fig. 2, an enlarged view of my improved device for keeping the cable taut looking at the ends of the sheaves.

In the drawings similar reference characters indicate corresponding parts throughout both views.

The base 1 of the Windlass is made, preferably, of a cross shape, having a cross-beam 2 at the end of each arm, said base being adapt.- ed to be buried in the earth. A vertical shaft 3 is journaled in the base 1, on which is loosely mounted the drum 4. If desired, a raceway may be provided in the base 1, in which antifriction-balls may be mounted and on which the drum 4 is seated. The edge of the base of the drum is provided with ratchetteeth 5, 6 being a spring-actuated pawl mounted on the base 1 to engage said teeth[ The top of the drum 4 is provided with a clutch-face 7 to receive a similarly-cut face 8 on clutch-block 9, splined on shaft 3, 10 being a lever for throwing the faces 7 and 8 into and out of engagement with one another, said lever being fulcrumed on journal-box 11 near the upper end of shaft 3. The ournal-box 11 is held in position and the shaft 3 braced by means of rods 12, secured to said box 11 and to the arms of the cross-shaped base 1. The upper end of shaft 3 has secured thereto a sweep 13 for rotating it, it being understood that the drum 4 is thrown into and out of gear with the shaft by means of clutch-block 9.

14 represents the cable, one end of which,

is secured to the stump to be extracted. In

devices of this character the other end of the cable is either secured to the Windlass or the services of a man are necessary to keep the cable taut on the drum.

My invention contemplates the provision of a structure to keep the free end of the cable taut on the drum and save the expense of the services of a laborer for this purpose.

To this end my improvement consists of two sheaves 15 and 16, circumferentially grooved, as shown in Fig. 2, to receive the cable 14, the sheave 15 being journaled between one of the rods 12 and angular brace 17. Sheave 15 is driven by means of shaft 18, journaled in boxes 19, secured to rod 12 and having at one end a beveled gear 20, that meshes with beveled gear-face 21 on drum 4, and beveled gear 22 on its other end, that meshes with beveled gear-face 23 on sheave 15, said gearing being so arranged that the surface of the sheave travels at the same speed that the surface of the drum does. Sheave 16 is journaled in the ends of a U- shaped bracket 24, having slots 25 therein to receive the extended ends of the axis 26 of sheave 15, and has a set-screw 27 in its upper end, that rests on angular extension 28 of brace 17. It will be understood from this construction that by operating set-screw 27 sheaves 15 and 16 may be brought into close proximity to embrace the cable 14 when the drum is inoperation, or the sheaves may be separated to permit the cable to be freely passed, between the sheaves to reset the machine. The brace 17 is slotted, as shown at 28*, to permit adjustment of sheave 16, as stated.

Having'thus described my invention, what I claim is 1. In combination with a Windlass, rods to brace the top of the Windlass, a sheave journaled on one of said rods, said Windlass and sheave geared for simultaneous operation, and another sheave adjustably mounted relative to said journaled sheave, substantially as shown and described.

2. In combination with a Windlass, rods to brace the top of the Windlass, an angular brace secured to one of said rods, a sheave journaled in said rod and angular brace, said sheave and Windlass geared together for simultaneous operation, a U-shaped brace adjustably mounted on said angular brace, and a sheave journaled in said U-shaped brace, substantially as shown and described.

3. In combination with a Windlass, rods to ICC brace the top of the Windlass, an angular brace secured to one of said rods having a slot therein, a sheave journaled on saidrod and angular brace, beveled gear-faces on said 5 Windlass and sheave, a shaft having beveled gear-pinions on its ends to mesh With the respective gear-faces, a U-shaped brace having slots therein in Which are mounted the ends of the axis of the sheave aforesaid, a sheave 1o journaled in said U-shaped brace having its axis extending through the slot'in the angular brace, and a set-screw secured in said U- shaped brace and bearing against the angular brace to adjust the sheave journaled in I the U-shaped brace relative to the other l sheave, substantially as shown and described.

In testimony whereof I hereto aflix my signature in the presence of tWo Witnesses.
